Bi-flow filter drier with flare and cu-plated solder connectors, type DMB/DCB
Selection example
Select the appropriate type (DMB or DCB) based
on refrigerant and oil type. Then select the drier
size based on the adsorption and liquid capacity
required.
a. Amount of charge: 15 kg R 134a at t L = 24°C
To dry 15 kg R 134a at 24°C from 1050 to
60 ppm moisture, a DMB 16 is necessary.
b. Cooling capacity: Q e = 25 kW
To obtain a mass flow corresponding to 25 kW
cooling capacity with a DMB 16 filter drier, a
1
/ 2 inch connection must be chosen.
Larger connections can be chosen in
accordance with the liquid line dimension.
c. Result
DMB 164 or DMB 165 can be used.
If the initial moisture content is very small or a
planned change of the filter drier is considered, a
smaller filter drier size can be chosen.
